R12 was a major release for OPM in the sense it merges process inventory with discrete inventory which resulted into streamlining of inventory operations & better integration with Order Management, Purchasing etc. Another change was the introduction of SLA for OPM, which finally hit the nail in coffin for much criticized MAC module. Afterwards, there are lots of enhancements like Multi-batch operations, Make-to-Order Functionality, Landed cost management etc. We now even have validated integration between 3rd party Regulatory document generation partners and OPM Regulatory Management. But, something was still missing. Something that process manufacturer is demanding from Oracle from long time??
